Title: Method of compensating thermal displacement of ball screw, and machining tool thereof
Inventor: KAWAGUCHI KOICHI
IPC: B23Q15/18
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a position detecting method in which a detected position can be precisely compensated with the use of only one tactile sensor in consideration with an affect caused of thermal expansion for every section of a ball screw. SOLUTION: In a position detecting system 10, a ball screw 2 is rotated by a motor 1 so as to move a table 3 threadedly engaged with the ball screw 2, and a position of the table is detected by a position detector 4. In this arrangement, the table 3 is mounted thereon with a tactile sensor 5, and a contact jig which is not subjected to affect by a thermal change is located at a position which is previously determined along the travel path of the tactile sensor 5. The tactile sensor 5 is moved as the table 3 is moved, and accordingly, detected positions of the table 3 are compensated in accordance with a position which is detected by the position detector 4 when the contact sensor 5 is made into contact with the contact jig J.

Abstract: PURPOSE:To remove easily jammed paper and a card emboss, by a method wherein a cam mechanism for lowering an imprint roller to a position of an upper surface of the card emboss is established, and a solenoid for keeping a plunger interlocked with this cam mechanism at a position wherein this roller is lowered by attracting the plunger by magnetic force is arranged. CONSTITUTION:A link 3 is made to perform pendulum motion with a driving motor, and a carrier 4 is slided on a shaft 1. In that case, a roller look of a cam mechanism attached to the carrier 4 is moved along on a cam face of a stopper, and a look shaft 10 is moved along the cam face of this roller lock. Thereby, an imprint roller 2 becomes under a state therein it is lowered to a position of an upper surface of a card emboss. At that time, a solenoid 6 is excited, and a plunger 7 of the roller lock 5 on the career 4 is attracted to keep the imprint roller in a lowered state. Then, when jam occurs, the solenoid 6 is demagnetized, the imprint roller 2 is made to take refuge upward, and jammed paper is removed.

Title: Sorting device
Inventor: ITOU YASUTOSHI
IPC: B65G47/44
Filed: 1990-02-05
Abstract: PURPOSE:To prevent articles from being damaged and to enhance the availability of a sorting device by transferring cut and sorted articles by a horizontally conveying means to a fabric type storage mechanism provided to the horizontally conveying means, projected in a conveying direction and movable in a vertical direction about the outlet end of the conveying means as a fulcrum. CONSTITUTION:An article 16 fed from a supply conveyer 1 is pushed out onto a conveying means 3 by means of a push-out mechanism 2 at a sorting position, and is moved n a direction B above the conveying means 3. At this time, a pooling mechanism 4 composed of a fabric part 7 is operated by a cylinder 12 so that the fabric part 7 is inclined downward. Accordingly, the article slides down on the fabric part 7, and is stored in a storage box which is not shown. Further, the cylinder 12 extends to cause the fabric part 7 to stand upright during replacement of the storage box with another one for changing batch modes. Accordingly, even though a sorted article 16 in the next batch mode is fed soon, the article 6 allows to strike upon the fabric part 7 with no shock, and to stay once in a downward bulged part of the fabric part 7. Thus, it can be prevented from being damaged, thereby it is possible to enhance the availability of the sorting device.

Title: Sheet sorter
Inventor: MATSUO KAZUHIRO
IPC: G03G15/00
Filed: 1988-02-08
Abstract: PURPOSE:To prevent increase of size by arranging a switching means in the upstream of the sheet discharge port for a bin tray, and guiding the sheet to the sheet discharge port when a carry path is not switched while guiding the sheet to a guide groove when the carry path is switched. CONSTITUTION:A flapper 5 functions as a carry guide for feeding a sheet to a pair of carry roller 6 under normal copy mode of a copy machine 1. When the sheet is inverted temporarily and subjected to perfect copy through the copy machine 1, the flapper 5 provides an operational signal to a solenoid 50, which then attracts a plunger 51 and rotates counter clockwise thus guiding the sheet to a guide groove 52. Since an inverting flapper mechanism can be adapted initially, the size of a sheet sorter does not increase thus reducing cost.

Title: Inforamation signal recording and reproducing device of rotary head system
Inventor: ENDOU KENJIROU
IPC: H04N5/7826
Filed: 1984-02-14
Abstract: PURPOSE:To improve the continuous performance of a track between the old and new recorded parts by providing a gain control means for tracking error signal and increasing the gain of the tracking error signal to a specific section. CONSTITUTION:A magnetic tape 71 is driven toward an arrow head 75 by a capstan 73 and a pinch roller 74 which are driven by a motor 72. While the output of an amplifier 79 is applied to a tracking error detecting circuit 85 after a tracking detecting pilot signal only is extracted by a filter 82. Here a level difference is obtained between pilot signals of two adjacent tracks and delivered as a tracking error signal. This error signal is applied to a gain variable circuit 86, and the weighting is applied to a weighting section decided by a signal processing circuit 80. Then the motor 72 is driven via a motor drive amplifier 87. This reduces the track discontinuity in an after-recording mode.

Title: Control drive of sensor-less dc brush-less motor
Inventor: SHUKURI YOICHI
IPC: H02P6/08
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To conduct stable switching without causing out-of-step by decreasing a difference in the phase between the commutating timing signal of a position detecting signal and a forced synchronous signal using a logical operation means which generates an energizing timing signal with a terminal and a reference voltage comparison signal, thereby conducting stationary sensor-less operation. SOLUTION: In switching forced synchronous starting to sensor-less driving by periodical-controlling a forced synchronous signal, a starting command is made by a rotation starting signal 43. A time measuring timer C38 outputs the forced synchronous signal, and a driving base signal state switching and signal latching means 41 generates a forced synchronous signal. The inductive voltage of a stator coil generates a position detecting signal by means of the rotation of a rotor. A time measuring timer B35 generates the commutating timing signal of the position detecting signal. If the cycle of the forced synchronous signal is beyond the data cycle of a data memory part 40, a commutating timing phase difference measuring means 36 measures a difference in the phase between the output signals of time measuring timers B, C.  If it exceeds its threshold value, an operation switching means 37 conducts switching to stationary sensor-less operation.

Abstract: PURPOSE:To reduce the winding production man-hours remarkably by a method wherein duct pieces are protruded upward beyond the upper part of winding to be bound one another passing through holes made into the protrusion. CONSTITUTION:Duct pieces 3 made longer than the width of sheet coil are protruded upward beyond the upper part of winding. Then through holes 5 are made in the protrusion of duct pieces 3 in the radial direction to pass the string for binding the duct pieces 3 through the holes 5 after winding work preventing the pieces 3 from falling down. Through these procedures, the winding production manhours may be reduced remarkably since the through holes 5 are made straight side by side in the radial direction protruding upward beyond the upper part of winding to make the string pass through the hole 5 much easier.
